Analysis of the Hydrologic Response Associated With a Shutdown and Restart of the 200-ZP-1 Pump and Treat System

Description: A number of programs have been implemented on the Hanford Site that utilize the pumping and treatment of contaminated groundwater as part of their remediation strategy. Often the treated water is reinjected into the aquifer at injection well sites. The implementation of remedial pump and treat systems, however, results in hydraulic pressure responses, both areally and vertically (i.e., with depth) within the pumped aquifer. The area within the aquifer affected by the pump and treat system (i.e.… more

Automating the management of environmental compliance reporting: Making the complex simple

Description: Environmental compliance reporting requirements are notoriously complex. This reporting complexity is compounded by organizational and functional complexity at Rocky Mountain Arsenal (RMA), where the Department of the Army has undertaken a multi billion dollar environmental cleanup action. This site is subject to both fixed and contingent federal, state, and local reporting requirements. Management and operation of the site is characterized by numerous organizational layers, and compliance info… more

Availability Analysis of the Ventilation Stack CAM Interlock System

Description: Ventilation Stack Continuous Air Monitor (CAM) Interlock System failure modes, failure frequencies, and system availability have been evaluated for the RPP. The evaluation concludes that CAM availability is as high as assumed in the safety analysis and that the current routine system surveillance is adequate to maintain this availability credited in the safety analysis, nor is such an arrangement predicted to significantly improve system availability.

Biosphere Dose Conversion Factor Percentiles for Radionuclides Identified as Being Potential Contributors to Dose After Ten Thousand Years

Description: Two previous Analysis and Modeling Reports (AMRs) Civilian Radioactive Waste Management Systems Management and Operating Contractor (CRWMS M&O 2000a and CRWMS M&O 2000b) provided abstractions of the biosphere dose conversion factors (BDCFs) for those radionuclides determined (CRWMS M&O 1999a) to be of potential importance for the initial ten thousand years after closure of the repository. To continue predictions of dose beyond ten thousand years requires abstractions of the BDCFs fo… more

Brazil's Economic Reform and the Global Financial Crisis

Description: Despite backing from the International Monetary Fund (IMF), capital flight from Brazil in 1998 prompted the government to jettison its pegged currency stabilization program and float the real on January 15, 1999, becoming another casualty of the volatile international capital markets. Brazil adjusted to its financial crisis faster than expected, which is considered over. This report provides a final summary of Brazil's financial crisis and related IMF assistance in support of Congressional inte… more

Bridged polysilsesquioxanes: A molecular based approach for the synthesis of functional hybrid materials

Description: Bridged polysilsesquioxanes (BPS) are a family of hybrid organic-inorganic materials prepared by sol-gel polymerization of molecular building blocks that contain a variable organic component and at least two trifunctional silyl groups. The resulting xerogels and aerogels have physical and mechanical properties that are strongly influenced by the organic bridging group. This talk focuses on the synthesis of functional bridged polysilsesquioxanes. Incorporation of functional groups that respond t… more

Calculation of Hamaker constants in non-aqueous fluid media

Description: Calculations of the Hamaker constants representing the van der Waals interactions between conductor, resistor and dielectric materials are performed using Lifshitz theory. The calculation of the parameters for the Ninham-Parsegian relationship for several non-aqueous liquids has been derived based on literature dielectric data. Discussion of the role of van der Waals forces in the dispersion of particles is given for understanding paste formulation. Experimental measurements of viscosity are pr… more

Canister Storage Building Receiving Pit Modification Informal Design Verification

Description: The design for modifications to the CSB Cask Receiving pit guides was verified by the informal design verification (meeting) method on August 9, 2000. The invited list of attendees and the meeting attendance sheet are included in attachment 1. The design modifications that were reviewed are documented in ECN 654484 (attachment 2). The requirement that the design is to be verified against is to ''center the transportation cask sufficiently to allow installation of the guide funnel on the cask ({… more

CARBON DIOXIDE AS A FEEDSTOCK.

Description: This report is an overview on the subject of carbon dioxide as a starting material for organic syntheses of potential commercial interest and the utilization of carbon dioxide as a substrate for fuel production. It draws extensively on literature sources, particularly on the report of a 1999 Workshop on the subject of catalysis in carbon dioxide utilization, but with emphasis on systems of most interest to us. Atmospheric carbon dioxide is an abundant (750 billion tons in atmosphere), but dilut… more

Characterization Plan for Establishing a PCB Baseline Inventory in Hanford Waste Tanks

Description: In May 2000, the U.S. Department of Energy, Office of River Protection (DOE-ORP) and the U.S. Environmental Protection Agency (EPA) conducted meetings to discuss management of polychlorinated biphenyls (PCBs) in the Hanford tank waste. It was decided that the radioactive waste currently stored in the doubleshell tanks (DSTs) will be managed to comply with the Toxic Substance Control Act (TSCA) (40 CFR 761). As a result, DOE-ORP directed the River Protection Project tank farm contractor to prepa… more

Characterization, Washing, Leaching, and Filtration of C-104 Sludge

Description: Approximately 1,400 g of wet Hanford Tank C-104 Sludge was evaluated by Battelle for the high-level waste (HLW) pretreatment processes of ultrafiltration, dilute caustic washing, and elevated-temperature caustic leaching. The filterability of diluted C-104 sludge was measured with a 0.1-{micro}m sintered metal Mott filter using a 24-inch-long, single-element, crossflow filtration system (cells unit filter [CUF]). While the filtrate was being recirculated prior to washing and leaching, a 6.9 wt%… more

CHEMISTRY OF SO{sub 2} ON MODEL METAL AND OXIDE CATALYSTS: PHOTOEMISSION AND XANES STUDIES

Description: High-resolution synchrotron based photoemission and x-ray absorption spectroscopy have been used to study the interaction of SO{sub 2} with a series of metals and oxides. The chemistry of SO{sub 2} on metal surfaces is rich. At low coverages, the molecule fully decomposes into atomic S and O. At large coverages, the formation of SO{sub 3} and SO{sub 4} takes place. The following sequence was found for the reactivity of the metals towards SO{sub 2}: Pt {approx} Rh < Ru < Mo << Zn, Sn… more
